Abstract

The present invention relates to a portable device (1), to a system and to a method for monitoring radiological risk, using at least one ionising radiation sensor (10) coupled to a control unit (11) capable of quantifying the detected radiation and integrated into the portable device (1), which is miniaturised in the form of a wristwatch comprising: - at least one first communication module (12) for communicating, via at least one first integrated antenna (120), with a remote monitoring device (2); - a geolocation module (13) configured to determine and track the geographical position of the portable device (1), via at least one second integrated antenna (130), wherein the control unit (11) is capable of transmitting the aggregated collected information, together with the consecutive positions, to the remote monitoring device (2), thereby providing an automatic mapping of the radiological risk at the site where the wristwatch is worn.

Abstract

A device for measuring the concentration of a gas that makes up ambient air comprises a wristwatch comprising a watch case (13) containing a watch movement, time indicating members (1, 3, 9) visible through a crystal of the watch case (13). The wristwatch furthermore comprises at least one sensor (11) designed to measure the concentration of a gas involved in the makeup of the ambient air. The wristwatch also comprises means for actuating an alarm when the gas concentration measured by the sensor (11) reaches or crosses a threshold. The device has two operating states: a "time" state and an "alarm" state, in which states, in the "time" state, the time-indicating members (1, 1 ', 3, 9) indicate time and the sensor (11) constantly measures the concentration of gas without displaying it or activating the alarm. If the sensor (11) detects a concentration of a gas, the device switches into "alarm" state in which the indicator member (4, 4', 8, 9, 10) displays this measured value and/or the means for actuating an alarm actuate an alarm normally without the time being displayed.
